Vapi Tool Management

Choose the documented tool type that directly provides the requested capability. Default to a payload or implementation plan unless the user explicitly requests a live Vapi mutation.

Safety and Source Rules

• Verify the type and every field against the current Create Tool API, public OpenAPI schema, or type-specific public guide before using it.
• Never imitate a documented Vapi capability with a custom function tool.
• Never invent an endpoint, request schema, destination, phone number, assistant ID, tool ID, integration connection, credential, or secret.
• Keep secrets in Vapi credentials or the user's backend. Treat an MCP server URL containing a token as a credential.
• Distinguish tool configuration, assistant attachment, provider connection, and external implementation. They are separate deliverables and success in one does not imply success in another.
